TOKYOWELD TechnologyOur technology

Our main products are for handling the so-called post-processes of electronic component manufacturing, which are electrical measurement/testing, optical inspection, and packaging. By utilizing its basic proprietary technology of high-speed component carriage and by combining various electrical measurement/testing, optical inspection, packaging, and other modules, we constantly develop new technologies to create new value.

New products that cater to both known and potential needs of customers must embody sophisticated technology in the following five fields: machinery, control, electronic circuitry, measurement, and image processing.

Tokyo Weld has been conducting R&D for many years in a wide range of fields related to the post-processes of electronic component manufacturing. In recent years, Tokyo Weld has also been venturing into new technological domains in the pursuit of novel ideas that may prove useful to its customers, based on research findings and technology development. Expert engineers in diverse fields are constantly engaged in technology development, focusing on their respective objectives. In addition, Tokyo Weld has been collaborating with certain customers, universities, and other institutions to enhance its technology - tirelessly repeating the cycle of research, idea conception and prototyping, trial and verification, and improvement.

Five years of fundamental technology training

Five years of fundamental

technology training

We believe that engineers who develop highly specialized products must possess a basic knowledge of machinery, control, electronic circuitry, measurement, and image processing, while also being an expert in one of these fields.
To develop such engineers, Tokyo Weld requires all new employees to attend lectures and experiments where they are taught the basics of all the aforementioned fields for three years, after which they move on to pursue one of the fields as their specialty, depending on their career aspirations and personal aptitude.
In this training regimen, effective learning is only attained through the right mixture of lectures and experiments. Tokyo Weld makes utmost effort to ensure its employees achieve effective learning through flexible curriculum design that values a good balance between on-the-job training (where they perform actual operations) and theoretical studies.

1st and 2nd yearsLearn the basics of all fields.

3rd through 5th yearsSpecialize in one of the fields.

Our five key technological fields

01Component carriage
This is the technology that underpins the carriage capability of the machines to convey, measure, and package miniscule electronic components at high speed with precision.
The technology uses devices such as motors, actuators, and air valves to form micro-mechanisms that perform fast, high-precision carriage of miniscule electronic components weighing less than 1 mg each, taking into account fluid mechanics and delivering high operational accuracy. In terms of academic disciplines, the technology is rooted in mechanical engineering, precision engineering, electromagnetism, and electrical machinery and apparatus.
This technology controls motors, actuators, air valves, and other driving units of the machines accurately at high speed and helps to establish device motion technology. The technology also serves as a link between electronic instruments, image inspection equipment, and component carriage equipment. Its suite of software libraries is based on the ladder and C programming languages. The key elements of this technology are control technology and information processing technology.
03Electronic circuitry
This technology concerns electronic circuitry and underpins control, imaging, and measurement technologies. It is comprised of analog and digital technologies, which include large-current circuits as part of analog technology. In terms of technological disciplines, it is based on electrical and electronic engineering.
This technology is for measuring the electrical properties of electronic components by flowing electricity through them. As for the types of electric current, both DC and AC (i.e., low-frequency, high-frequency, microwaves) are used to form a system for inspecting the characteristics of electronic components and determining their conformity/non-conformity to the specifications. In terms of technological disciplines, the technology is founded on electrical and electronic engineering.
This technology is for taking images of electronic components and inspecting them to see if they have any visible flaws or issues on their exterior. The technology can be broken down into three elements: lighting technology, image acquisition technology, and information processing technology. These three technological elements are based on lighting optics, applied physics, and information processing engineering, respectively. In recent years, the use of artificial intelligence (AI) has been introduced to the discipline of information processing.

Joint research with universities

In order to find novel approaches and ideas to problem solving, it is essential to constantly acquire new knowledge in various specialized fields, in addition to the information obtained from customers.
To this end, Tokyo Weld collaborates with universities specialized in relevant fields and conducts joint R&D projects, and university staff attend internal conferences to serve as advisors.
Depending on the research topic, our technical teams give public presentations on such activities, exchange ideas with collaborating researchers, and build a network of key academics and professionals, which may provide important clues for solving problems.
